Thank you !
The letter B and Y in busy could be in a different color than the U and S so that people get the message more easily.
We've been and are still thinking about that. We may keep it like more disguised, and known by some ppl, or to-be-discovered (When you ask yourself why Busy ? like you did), than something really obvious playing with the logo letters/colors etc. (something i'm not real fan of..)
Also regarding author rewards, you could display the amount more precisely like $0.001 or even $0.0001 so that even people with little influence can see the counter move up when they upvote.
Our solution will cover this issue. When you vote on a post you will have a small animation showing exactly the added amount to the payout you just made, also you'll be able to click and view all details, the same way you can see it on steemstats, or steemd
thanks for your kind suggestions
